Cisco Cisco IOS Software Release 12.4(23) Notas de publicación

This section contains the following sections with information that is specific to the Cisco 1900 series 
routers:

The Cisco MWR 1900 series of routers consists of the Cisco MWR 1941-DC Mobile Wireless Edge 
Router, which is a networking platform that is optimized for use in mobile wireless networks. Cisco IOS 
Release 12.4 supports the Cisco MWR 1941-DC router for use at a cell site edge as a part of an IP Radio 
Access Network (IP-RAN).

Future releases of Cisco IOS Release 12.4 may support the Cisco MWR 1941-DC router for use at a cell 
site edge as a part of a cell site Data Communications Network (DCN).

The Cisco MWR 1941-DC router offers high performance at a low cost while meeting the critical 
requirements for deployment in cell sites, including small size, high availability, and DC input power 
flexibility.

The Cisco MWR 1941-DC router provides two fixed LAN 10/100 BASE-T Ethernet ports and three 
WIC/VIC expansion slots (however, the third slot is supported in a DCN implementation only, as is the 
single network module slot).
